MACHINE FOR SECURING FlLAMENT-HOLDEHS INTO THE GLOBES 0F INCANDESCENT LAMPS.

Specification of Lettera Patent.

Patented Aug. 28, 1906.

.To all whom it may conc/ern:

Be it known that I, GEORGE P. Menon L NELL, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and 4useful Improvement in Machines for Securing Filament-Holders into the Globes of Incandescent Lamps, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to to make and use the same, reference being had to the accompanying drawin s, forming part of this specification, in whic J Figure 1 is a top plan view of a machine for securing filament-holders into bulbs of incandescent lamps constructed in accordance with my invention. Fig. 2 is a view of the machine, pvartly in section and partly in elevation. ig. 3 is an elevationa view, partly in line 3 3 of Fig. 1. Fig. 4 is a fragmentary plan view of a slightly modified form of machine, and Fig. 5 is a iront elevational 'view of the same.

This invention relates to a machine for securing filament-holders into the bulbs of incandescent lam s.

One of the objects of the invention is to provide means whereby the ilaxnent-holder may be sealed into the lamp-bulb in an eilithrough the medium of heat, whereby the parts are fused together.

Another object of the invention is to provide means for adjusting the flame to suit various conditions.

A still further object of the invention is to provide means whereby the burners may be positioned in propel' relation to the parts to )e fused, so as to obtain the best rcsu ts; and another object of the invention is to arran e the mechanism so as to be most convenient y accessible and easily controlled by the operator.

Referring now to the drawings, 1 designates a suitable base on which may be secured one or more mechanisms for sealing the filament- In the present instance I have illustrated two sets of mechanism arranged in multiple, whereby both sets may be operated by a .nngle trcadle. At convenient points on the table I arrange duplicate rastnrrs 2, comprising flanges secured to the table or base l, and having central vertically-armilged tubular bearings 3,

l which at their respective ends bear against a hollow shaft 4, confined within the tubular bearings, each of said shafts carryin a pulley 5. The lower extremities of the hol ow shafts 4 are provided with plugs Greeting in bearings in brackets 7, which bearings in the brackets take up the en d-thrusts of the respective shafts 4. The hollow shafts 4 carry springpressed friction-pins 8, which bear against verticallyadjustable and frictionally --held filament-holder spindles 9, which comprise elongated rods projecting through the hollow shafts 4 and having on their lower ends knobs or buttons IO, the upper ends of said rods being beveled, as shown in the drawings, and provided with a bore or o ening to receive the leadin -in wires of the amont, as shown in dotted ines in Fig. 2.

On the upper extremities of the shafts 4 are collars 11, which support adjustable bulbholders l2, having seats 13 for the reception of the glass bulbs. These seats are arranged so that if a filament-holder is sup orted on the end of one of the spindles 9 an a bulb is su orted within the seat 13 of one of the bu -holders said filament-holder and bulb will be caused to aline in such a manner that by applying heat to their respective lower extremities they will be fused together. The heat is preferably applied by two sets of burners I4 and 15 diametrically opposite each other and carried by T connections 16 and I7 in communication with the pipes or tubes 18, connected to a suitable fuel supply, the intermediate portions of the tubes, as at I9, being of some suitable flexible material.

In order to obtain the best results, it is dclar point, and this diuln of the blow set for each set o burners, which nozzles are connected to a suitable air-supply through the medium of th pipes or tubes 22, connected to the branches 23 and 24. In each branch is provided a valve designated by the numerals 2,5 and 26, respectively, and by manipulating the valves the air-su ply may be controlled. Means is provider for permitting the vertical adjustment of the heating apparatus just described, which means is best illustrated in Figs. 2 and 3.

By reference to Fig. 3 it will be observed that a trcadle 27 is fulcrunied at 28, and at is done through the ineipe-nozzles 20 and 21, one

ICS

.i and the arms may one" end of ed to an adjustin -rod 30, which adjustingrod passes throug a verticalguide 31 and is also guided by an auxiliary guide 32, passing through an opening in the table or base. On the upper en d ofthe adjusting-rod 30 are oppositely-dis iosed arms 33 and 34, having in their ends elongated slots35 and 36, through each of which a pivot-fastening device 37- rojects, which fastening device also projects through elongated slots 38 and 39 in the pivoted burner-carrying arms 4() and 41K, also supporting the blowpipe-nozzles. Thus it will' beseeii that by depressing the forward end of the treadle 27 the heating mechanisms may be simultaneously raised, and their weights will be sufficient to lower them when pressure is relieved on the treadle, By providing the elongated slots in the arms 33 and 34 and fastening'the sl'ott arms 40 and 41 thereto the lcrum of any of the arms may be moved toward or away from the axis of the lamp-carryingl mechanism, be swung on either fulc mi, so as to adjust the burners and blowpipe-nozzles toward or away from the lamp, as occasionlmay demand. The adjustment may further be controlled byl swinging either of the arms 33 or .34 on their pivot-fastening device 42.

In ogeration the hollow shafts 4 are driven throng the' medium of a belt 43, which passes around a drive-pulley 44, .driven by suitable power, said belt also passing over an idler 45, preferably suspended from a bracket 4B, supported by the base or table 1, and thence around the ypulleys 5 on the respective hollow shafts 4.

It will be understood that the shafts 4 rotate continuously, and accordingly the s indles 9 also rotate continuously, due to t eir frictional connection with said shafts. When placing a bulo and a filament-holder in o erative position, the operator grasps the nb 19 on the lower end of the spindle 9 and moves said spindle upwardly until the upwardlysprojecting sto on said knob engages a ortion of the brac et 7, as shown at the left of 2, whereby said spindle is held at 4 continues to rotate.

rest while the shaft The o erator then takes a filament-holder with tilie leading-in wires' projecting dow n wardl therefrom and places it on the upper end o the spindle 9, which is at rest, the beveled upper epd of said spindle aiding the operator greatl in guiding 'the leading-in wires into the bore of said spindle. After the lament-hold er has been placed in position the knob 10 is again ras ed and the spindle 9 ulled downwardy t e operator, taking .a amp-bulb in her other hand and dropping it intothe constantly-rotating bulb-holder 13 over the filament-holder, the s iindle 9 at the sametimeA being 'raised or owere to properly position the filament-holder thereon the treadle is a pitman 29, connect-i burner-carrying i with reference to the neck of the lamp-bulb,

-the spindle 9 being then released, so that it tion between the spindle 9 and the shaft 4is,`

for it enables the operator to hold said spindle at rest while she is lacing the filamentholder thereon and also enables her `to quickly and accurately position. said filamenthollcer relatively to the neck of the lampbu If desired, the stop on the knob 10 'may not be used, as the operator can hold the spindle 9 at rest with one hand while she places a filament-holder thereon with the other hand. In placing the lamp-bulb in position the shaft may or may not be stopped; but if it is desired to prevent rotation of the shaft this can .be done by securely holding the shaft, be-

cause the belt Which'drives it is merely a friction-belt, and one shaft may be stop ed without aietting the movement of the ot er. In view of the fact that theA shaft vcontainsa spring-pressed friction-pin 8, the spindle9 will; e held in any vertica'lradjustment and vertical movement may be imparted thereto with ease and convenience.

In Fi s. 4 and 5 l have illustrated a slightlymodifie form of controlling mechanism, and while the iping, burners, and blowpipe-nozzles are al arrangedsimilar to the constructions illustrated in Fi s. 1 to 3 the mechanisms are so arran ed t at vertical movement may be imparte( to the burners and blowpipes for one bulb-holder without affecting those cooperating with the other holder.

The treadles 47 and 48 are supported by a suitable base 49, and each treadle is connected to a pitman 50. The upper extrem# ity of' each pitman is connected to a verticallymovable burner-support 51, havin an arm 52 pivoted thereto, and at Vits en distant from the burner-support 51 vided with an elongated slot 5B, through ,which projects a pivot-fastening device 54,

also extending Vthrough an elongated Vslot 55 in one end o a burner-su )orting arm 56, which also supports the lowpipe-nozzles. A bracket 57 is carried by the arni 52 to support the opposite set of burners and blowpipe-nozzles. The belt for drivin 4 the shafts 4 used in the form illustrated in `igs. 4 and 5 is substantially the same as that applied to the construction shown in Figs. 1 to 3, and it is therefore not deemed necessary to specificallyFr describe it again.

The essential difference between the constructions illustrated in Figs. 4 and'5 and the construction illustrated in Figs. 1 to 3 is that the form illustrated in Figs. 1 to 3 contains the burner mechanisms arranged in multiple, while the construction shown in Figs. 4 and 5 illustrates these mechanisms as being separately operable. v
